To be fair only buddism is NOT against other religions. Christianity, for example, is really harsh with other religions. It doesn't suit me. I think I would belive in God if I never went to church or see people who are against other religions or gays JUST BECAUSE there's nothin about it in Bible.
I'm a human. I don't belive. I'm happy with it ^^ I don't care about who belives in what - it's a personal thing for everyone!

not religion. but everyone have to get heir own... paths? like someone is vegetarian for example.
Personally I would bann all kinds of religion to make people base only on ethics, but it cannot be done. People mainly need it... But I can see more harm that good things going from it.
So as for me - we don't need religion. As for world's case- it's needed.
So I cannot tell for sure.
